How I Met Your Mother: Legendaddy / Season: 6 / Episode: 19 (6ALH19) (2011)

Barney is excited to meet his real father, and hopes that they can run some Father/Son Pick-Up plays on women at the bar. One of the names of Barney's Father/Son play is called 'Father Knows Breast', a play on the title of the sitcom series, 'Father Knows Best'.

Marshall feels that the rest of the group has been treating him with kid gloves since his father's death. He sets out to prove his point by announcing that 'Phantom Menace' was by far the best Star Wars movie ever made.

Robin's 'knowledge gap' is that she didn't realize the North Pole is a real place. She thinks it's a made up place where Santa Claus lives, sarcastically saying that her journey to the North Pole would start in 'Narnia', go through 'Candyland' and end at Hogwarts, as she has been named the new Defense Against the Dark Arts teacher.
